Come on, folks. Let's call it. There are other good space games out there. It makes me sad, too, but... it's over, guys.
I've just started BFG, and I'm not too upset by official lines going as I was not relying on them anyway. There are many other spaceship lines that are serviceable and many more arriving all the time. If we look at how different the two GW Tau ranges were, we shouldn't have problems using alternative pattern ships for other races I think. Same applies if you look at previous and current ranges of any 40k race. Styles change quite dramatically over time, think of this switch as another of those.
There are also other space games out there, but I've not found any I like as much as BFG, and additionally what is to stop them going out of business at some point in the future with the same result? With BFG, same as with Epic, there are free rules documents that have been tested over time benefiting from extensive playtesting, and a community with a sense of self-reliance given that GW abandoned support long ago. The situation is not so bad I think.
